- Battery type — start-stop cars need EFB or AGM batteries which cost more than standard ones.
- Spark plugs — iridium plugs cost more but last much longer than standard copper.
In practice, both cars cost roughly £80–150 per year in consumables when you do the work yourself.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
